Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] The present invention will be further described below with reference to specific embodiments.

[0036] like Figures 1-4 As shown, this embodiment of a charging converter with a locking function includes a converter body 1, a first insert 2, and a locking mechanism 3. The converter body 1 includes a cover portion 11 and a body portion 12. The cover portion 11 has a mounting hole 111; the body portion 12 has a sliding groove 121, and a receiving cavity 122 is formed within the body portion 12 by a partition. One end of the first insert 2 extends into the inner cavity of the converter body 1 through the mounting hole 111; the locking mechanism 3 is located within the receiving cavity 122 and can slide within it.

[0037] The locking mechanism 3 includes a connecting rod 31 and a bracket 32 ​​connected to each other. The bracket 32 ​​is provided with a second insert 33. One end of the connecting rod 31 extends into the sliding groove 121 and is equipped with a sliding block 34. Under the action of the sliding block 34, the second insert 33 can pass through the mounting hole 111 and overlap with the first insert 2 to form a combined insert, so as to be inserted into the corresponding socket hole.

[0038] Specifically, such as Figure 2As shown, the mounting hole 111 is in a T-shaped structure as a whole, which comprises a first through hole 1111 and a second through hole 1112 in communication with each other. The first through hole 1111 has a larger opening width than the second through hole 1112. The first tab 2 is fixedly arranged in the first through hole 1111, and the second tab 33 is slidingly arranged in the second through hole 1112. Meanwhile, a stop block 35 is arranged on the inner side wall of the second through hole 1112 of the cover portion 11.

[0039] As shown in Figure 4 , Figure 5 The second tab 33 is away from the first tab 2 and has a protrusion 331 near the end portion. Through the cooperation of the protrusion 331 and the stop block 35, when the second tab 33 is not in use, the end portion with the protrusion 331 can be hidden in the mounting hole 111, which can not interfere with the use of the first tab 2 alone and can ensure the smooth sliding of the second tab 33.

[0040] In this embodiment, the second tab 33 is in a U-shaped structure formed by bending a copper sheet. The design of the U-shaped structure can generate a certain elastic force after the second tab 33 is inserted into the socket hole, thereby further improving the firmness of the plug-in.

[0041] The connecting rod 31 comprises a horizontal segment 311 and a vertical segment 312 connected to each other. One end of the horizontal segment 311 is connected to the side of the bracket 32 away from the second tab 33, and one end of the vertical segment 312 is connected to the sliding block 34. Preferably, the horizontal segment 311 is arranged at the middle position of the bracket 32, which can ensure the synchronization of the movement of the second tabs 33 at both ends of the bracket 32. In order to ensure the overall strength of the connecting rod 31, an inclined reinforcing segment 313 can be additionally arranged between the horizontal segment 311 and the vertical segment 312, so that the connecting rod 31 is in a stable triangular structure as a whole.

[0042] Meanwhile, a positioning column 36 is arranged in the accommodating cavity 122, which is located in the triangular area surrounded by the connecting rod 31 and is in close contact with the horizontal segment 311. Through the arrangement of the positioning column 36, the movement of the connecting rod 31 can be guided, and the movement distance of the connecting rod 31 can be limited. For details, Figure 6 As shown, when the horizontal segment 311 and the reinforcing segment 313 are moved to the position of the positioning column 36 during the movement of the second tab 33 into the inner cavity of the converter body 1, the inward movement of the second tab 33 is limited. At this time, the protrusion 331 of the second tab 33 is just located in the mounting hole 111. Similarly, referring to Figure 7 When the second tab 33 moves outward, when the horizontal segment 311 and the vertical segment 312 are moved to the position of the positioning column 36, the outward movement of the second tab 33 is limited.

[0043] To ensure a certain locking force when the sliding block 34 is stationary at a certain position, thereby preventing the position of the second insert 33 from changing, a spring 37 is provided at the sliding block 34 in this embodiment, which provides a certain self-locking force to the sliding block 34. Specifically, refer to... Figure 4 , Figure 7 As shown, two limiting plates 38 are provided near the sliding groove 121 within the sliding groove 121. The sliding block 34 is generally H-shaped, with one end located within the sliding groove 121 and the other end located between the two limiting plates 38. The spring 37, sleeved on the vertical section 312, is compressed and limited between the limiting plate 38 and the sliding block 34. The elastic force of the spring 37 provides a certain self-locking force to the sliding block 34. Of course, the limiting plate 38 needs to have a moving groove for the vertical section 312 to pass through and slide. In addition, when the second insert 33 is compressed and deformed, the spring 37 can balance the force on both ends of the connecting rod 31.

[0044] In this embodiment, a charging converter with a locking function allows for the following mechanism: When the clip inside the socket hole becomes loose, preventing a tight connection between the first insert 2 and the socket hole, the second insert 33 of the locking mechanism 3 can be pushed out and stacked with the first insert 2 to form a combined insert. This effectively increases the overall thickness of the insert, improving the stability of the connection between the insert and the socket hole. When the first insert 2 is tightly connected to the socket hole, the second insert 33 can be accommodated within the mounting hole 111 and does not participate in the insertion action. In this case, only the first insert 2 needs to be used for insertion.

[0045] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
